<div> <font size="2">Hall started producing Ultra wheels in 1981 through at least 2000 and there are several series, </font><font size="2"><font size="2">which is something people lose sight of</font>. Obviously, the newer they are, the less possibility of stress-cracking. Some series may be more prone to cracking than others- I dunno. None are marked as to what series or date of production. You'd have to reply on a bill of sale with your car or photos from old Hall catalogues to find which series you have and approximately how old they are. <br>
<br>
And the only real way to check for stress cracks is X-ray which requires the rim-halves to be off the car. Any visible cracks are likely to already be leaking air. Airports have x-ray equipment as well as better equipped engine machine shops. The last replacement rim-half EVOD Industries made cost the owner around $300 and had ZERO guarantee for road use. Call EVOD for more info- they make the things and certainly have more trusted up-to-date info than casual posts on the Internet- including this one. Good luck- J Deryke</font><br>

<div>Everyone: thanks for the input. I am always amazed at the wealth of information on this board. It looks like I will be pulling and inspecting wheels this weekend! :)<br>
<br>
</div>
I'd be curious to know how many Hall Ultra wheels were produced, and how many failed? Are there other owners still running these wheels?<br>

>>>He means he did not drive his car on a racetrack. That doesn't really mean anything, since a racetrack typically puts less stress on a wheel than a pothole-filled road does (although it does put higher side-loads on it, especially when sticky tires are fitted...)<br>
